GEORGE E. ALLEN, OF PHILADELPHIA, PENNSYLVANIA.

THREAD-WINDING MACHINE.

Specification of Letters Patent.

Patented July 15, 1913.

To all whom, it may concern.

Be it known that I, GEORGE E. ALLEN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and use ful ThreadlVinding Machine, of which the following is a specification.

This invention relates to thread winding machines and more particularly to winding of sectional spoolers, warp beams or individual spools and has for an object to pro vide a construction whereby the spools may be wound of uniform thickness and the side faces of the same built up so accurately that the danger of breaking down is eliminated.

In winding machines as heretofore constructed it has been proposed to utilize a traverse bar which is reciprocated adjacent the winding core and the threads are guided thereto over the surface of a rotating cylinder or drum. These machines have in practice been found open to many objections and defects, the principal disadvantage being that the threads lag behind the traverse bar so that the wound spool does not have a uniform thickness corresponding to the stroke of the traverse bar and consequently the sides of the spools break down unless supported or held by some exterior means. The use of such means in a sectional spooler or beam is neither practical nor possible.

In my present invention I have devised a mechanism for positioning and holding the threads as placed by the traverse bar upon the drive drum bet-ween the said traverse bar and the point of contact of the winding spool, the effect of which is to impart the same length of movement to the threads as the length of the stroke of the traverse bar, with the result that the sections on the winding spool are wound in a self supporting manner and the individual sections are complete and unitary. Furthermore a sectional spool may be split up into any desired number of sections without danger of loosening the strands or breaking down the body of the other sections.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a side elevation of a machine embodying my invention. Fig. 2 represents a plan of the same showing in addition the thread delivery cops. Fig. 3 represents a front elevation of the machine. Fig. 4 represents a detail of a portion of the traverse bar and thread regulating roll.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :1 designates the main frame of a thread winding machine embodying my invention. Rotatably mounted in this frame is the main operating shaft 2 carrying the driving drum 3 which is driven, in the present instance, through the gears 4L and 5, the latter being mounted on the stud shaft 6 carrying the fast pulley 7 and loose pulley 8.

9 designates a pair ofstandards fixed to the main frame 1 and preferably arranged vertically with respect thereto, one standard being at each side of the frame and carrying a yoke 10. Each yoke 10 is apertured to form a guide for the standard upon which it is mounted, in order to allow free sliding movement between the parts. The function of this connection will be understood when it is stated that the core 11 of the sectional spool or beam is carried by these yokes 10 and its position relative to the drive drum 3 is constantly changing owing to the increasing diameter as the thread is wound on said core. Since the warp beam in its formation rests upon the driving drum and is driven by the same, the gradual raising movement of the yokes will be apparent.

The beam core 11 carries at each end a head 12, either or both of which may be detachable therefrom so that the warp sections may be removed if desired. The heads 12 are suitably supported for rotation by means of pivots 13 which are respectively screwthreaded through the yokes 10 and held in adjusted position by means of the lock .nuts 14 or the like. It will thus be clear that the core 11 is freely mounted for rotation and is driven through frictional engagement with the surface of the drive drum 3. The

relation between the core 11 and the drum 3 is properly maintained, in the present in stance, by a weighted lever system comprising the rod 15 and pivoted lever 16. The rod 15 is connected at one end to one of the yokes 10 and at. its other end to the lever 16. A foot treadle 17 is preferably form-ed on the lever 16, while a counterweight 18 is also carried thereby which maintains a constant pressure on the core 11 to hold it in contactavith the drum 3. Of course pressure on the treadle 17 will raise the core 11 to inoperative position when it is desired to discontinue a winding operation.

10 designates a trav bar mounted for sliding movement in guide brackets 20 of the frame 1 with respect to whichthe said bar is adapted to reciprocate transversely to effect the desired movement or throw of the thread during the winding thereof. This bar is provided with a plurality of openings 21 spaced at suitable intervals throughout substantially the entire length thereof, each of which is adapted to receive one of the aforesaid threads. In order to effect the required reciprocation of the traverse bar 19, I preferably mount a clamping head 22 on the end thereof, which is secured in position by means of the set bolt 23, and connects the same by a link 24. to the rock arm This latter is pivoted at 26 to the bracket 27 of the frame 1 and carries on one end a cam roller 28 normally held in contact with the double side faced cam 29 by means of the spring 30. The cam 29 is fixedly secured to a stud shaft'31 upon which is a gear 32 meshing with a gear fixed to the main shaft 2, the said gearing giving the desired ratio of rotation to the cam in order to reciprocate the traverse bar ina proper manner.

3% designates bearing uprights carried by the frame 1 and forming supports for a pair of tension rollers and 36 which serve to guide the threads toward the traverse bar. It will be noted that the roll 36 is maintained in the proper position, in the present instance, by means of a weighted tension cord 37 which passes over the said roll.

The thread or threads are delivered to the tension rollers from a cop rack 39 adapted to suitably support a plurality of thread cops, while intermediate the said rack and tension rolls is a guide bar 40 having openings 41 therein to properly separate the threads and direct them to the winding mechanism,

12 designates, in the present instance, a pressure roll transversely disposed. across the frame of the machine and having surface contact with the drum 3. As here shown the roll 12 is provided with bearing spindles 43 which seat in open ended slots 44 of the brackets 45, these latter being fast to the frame 1 and serving to retain the roll 1 2 in operative position. In connection with these brackets 15, it will be noted that I have preferably provided a socket 46 therein to support the roll when it is removed from normal posit-ion. The result of the use of this roll 42, or its equivalent in connection with a winding machine is revolutionary in the art of sectional or warp beam winding and the product, which has heretofore been an unsatisfactory and makeshift spool or warp beam, is now wound in a perfect manner and each section is a complete unitary structure, the sides of which cannot break down or be come distorted.

lVith my novel roll in operative position, t-hatis between the traverse bar and the warp beam or sectional spool and supported on the drive drum 3, the yarn or threads are held in close contact with the drum and fed by the rolling or feeding movement of the drum 3 and roll 42. In addition to this action the said roll 4-2 prevents the thread from lagging behind the traverse bar and consequently the full reciprocatory value of the bar is imparted and each section of spool or beam is built up of uniform width and with perfect plane side walls. As a result a warp beam or spool when complete is made up of a plurality of perfect: sectional windings, any of which may be removed if desired and the individual sections remain intact and unitary. A further advantage of this construction lies in the fact that it is unnecessary to use a weight guide or other heavy device on the warpbeam during its building up. Such devices are exceedingly detrimental to the thread and are highly objectionable in the trade. The roll 42 performs all the necessary functions as far as tension of the thread is concerned and the spools are wound evenly, accurately and of the same dimensions.

It will be noted when the roll 42 is in operative or normal position that the threads between the said roll and the traverse bar are held under tension, so that transverse movement of the said bar 19 results in the threads being positioned exactly on the moving drive drum 3 which thus carries each thread to the spool. The movement will be perhaps clearer by considering each thread as made up of a succession of points, each point corresponding to an infinltesimal movement of the traverse bar and therefore as each point is located on the periphery of the drum it is conveyed circumferentially and delivered to the winding spool. The action above described is clearly illustrated in Fig. 2 where the traverse bar appears at the left extreme of its movement and the yarn or threads beneath the roll t2 are angularly disposed and extend in parallel lines to the right, as shown in this figure, a certain distance, and then are sharply turned to the left and delivered to the spool. The threads beneath the roll 4-2,

which appear to be lagging behind the traverse bar, do not in fact lag at all but each infinitesimal point of each thread represent-s a position of the traverse bar during its movement to the left. These threads do not move with the traverse bar after contacting with the drum and are held by roll 42 and move in a straight line to their respective positions on the spool. Thus on the return movement of the traverse bar 19, the threads at the extreme movement of the bar to the right would be disposed at an angle just opposite from that shown in Fig. 2 and be carried without any side movement on the surface of the drum to their proper place on the spool.

It will now be apparent that I have devised a complete unitary structure for winding threads on a sectional spooler in an exact and uniform manner and the resultant article is self supporting and independent of exterior means to retain the sections intact.

It will now be apparent that I have devised a novel and useful construction of a thread winding machine which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and While I have, in the present instance, shown and described a preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
